This matching 18-pin IC receives the serial data stream via its DIN (Data In) pin. It compares the incoming address bits with its local address pins (A0–A7). If the addresses match three times consecutively, the HT12D decodes the 4-bit data to its output pins (D8–D11) and drives the Valid Transmission (VT) pin high.

Copy both the downloaded HT12E.LIB and HT12E.IDX (and the corresponding HT12D files) from your extracted folder.
Once the library is installed, you can build a complete virtual RF remote control system. Circuit Components Needed HT12E Encoder IC HT12D Decoder IC Logic States (for input toggling) Logic Probes or LEDs (for output visualization) This matching 18-pin IC receives the serial data
To successfully simulate these components in Proteus, the following file types are typically involved:

This chip receives the serial data from the receiver module and converts it back into 12-bit parallel data. If the address bits match the transmitter's address, it validates the data.
Many users distribute these files as part of a "Proteus RF Project" zip file. This ensures the library matches the simulation schematic.
